Overview

The Arm architecture provides the foundations for the design of a processor or core, things we refer to as a Processing Element (PE).

The Arm architecture is used in a range of technologies, integrated into System-on-Chip (SoC) devices such as smartphones, microcomputers, embedded devices, and even servers.

The architecture exposes a common instruction set and workflow for software developers, also referred to as the Programmer's model. This helps to ensure interoperability across different implementations of the architecture, so that software can run on different Arm devices. 

This guide introduces the Arm architecture for anyone with an interest in it. No prior knowledge of the Arm architecture is needed, but a general familiarity with processors and programming and their terminologies is assumed.

At the end of this guide you can check your knowledge. You will have learned about the different profiles of the Arm architecture and whether certain features are architecture or micro-architecture specific.
